Some mutations have no or little effect due to the redundancy of the DNA code.
DNA consists of pairs of codons, which are made up of 4 different types of nitrogenous bases. Therefore, DNA is able provide enough unique codes for 4x4x4=64 different amino acids. However, only 20 types of amino acids exist, which indicates that 19/20 of those amino acids have at least more than 1 codon to encode it.
For example; If the codon ACU mutated to ACC, how that that affect the protein?
Well, it would not effect the protein at all, because both ACU and ACC encode the amino acid threonine.
In addition, some amino acids have very similar properties to other amino acids. Even if amino acid X was replaced with amino acid Y, the effect on the protein may be small or non-existing if X and Y share similar properties.

∙ 11y agoMutations have different effects according to the type of mutation and the region of DNA in which they occur. Some mutations do not affect the resultant protein because they do not change the amino acid that is coded for. These are known as silent mutations. For example, CCU and CCC both code for the amino acid proline. Therefore if a mutation changed the U to a C, a proline would still be added to the protein and the mutation would have no effect. Mutations that occur in the non-coding regions of DNA (introns) may also not have an effect, as these regions do not provide the template for functional products (eg. proteins).

What is the significance of mutations to living things?
Many, if not most, mutations are neutral, meaning that they have little or no effect on the expression of genes or the function of the proteins for which they code.
What effect does mutations have on variation?
genetic variation originates from mutations on which evolution depends on.
How mutation affect survival skills of an organism?
It depends on the mutation. Some mutations have no effect on survival, some mutations are lethal, and some mutations make an individual better adapted to its environment, so it will be more fit than those without the mutation, and therefore produce more offspring with the same mutation, which could change the allele frequency of a population.
Ultraviolet radiation can cause mutations in the DNA of skin cells that have been overexposed to the sun This mutated DNA has no effect on future offspring because?
Mutations may occur in the rna codons
What can cause changes in DNA sequences?
mutations
Why are some mutation not harmful?
Some mutations can be deadly, harmful, or have no effect. Correct, not all mutations are harmful. Some mutations could even have a positive effect and help the creature adapt.
What is the most likely effect of an error during DNA translation?
The most likely effect of an error during DNA translation is a mutation. Some mutations are beneficial, some are deadly and some are what is called "nonsense" mutations. Nonsense mutations have no benefits nor do they have any "bad" consequences.
Why do mutations that occur in the skin or nervous system tend to have little effect on the evolution of a species?
Most mutations that occur have a neutral effect, or none at all, so they would not affect evolution. Organisms with mutations that cause detrimental impact typically will not survive; therefore, they will not reproduce, and the mutation will not be passed on, so the species will not be affected overall. Beneficial mutations are typically the only mutations that will affect an organism's posterity and the evolution of its species, but good mutations are very rare. This is why most mutations have little effect on the evolution of a species.
What effect can mutations on a virus?
They create genetic variations.
Do all mutations affect the protein results?
No. Point mutations may have no effect on the protein, however, they can also be very harmful.
What is the conclusion of mutagenic effect of vodka on the phenotype of fruit fly?
some mutations include the change in eye color of the drosophila melanogaster
Mutations that occur in skin or lung cells have little effect on the evolution of a species because mutations in these cells?
cannot be passed on to offspring
How mutations might affect the traits of an animal?
it could alter the way the animal moves and how the body works

A characteristic of mutations is that they usually?
Mutations are random. They may be beneficial, detrimental, or have no effect at all.

genetic variation originates from mutations on which evolution depends on.
